1. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers
Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER
2. A method for analysing the traffic process in a safety perspective
Sammanfattning : The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. LÄS MER
3. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems
Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

4. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems
Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER
5. Road Safety Development Index : Theory, Philosophy and Practice
Sammanfattning : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. LÄS MER
